The enemies feel like they move faster and the death wall feels like it comes to you faster even on casual mode. If anything, casual should remove the death wall all together. I'm willing to bet people don't generally play this for the gameplay, but for the gallery, and if you make it harder and harder to unlock while also not saving progress between updates, well that's no good
Seriously, this game is legitimately frustrating now. A dog getting you is impossible to get out of because it recovers faster than you so you can't even crouch and get an attack off before you are jumped again.
I should not be winning a level by the skin of my teeth after failing it 5 times on Casual.
